Brief Summary

This study is a Phase I, open-label, single-centre, randomised, two-period, single-dose crossover study to compare and assess the bioequivalence, safety, tolerability and pharmacokinetics of hydroxycarbamide dispersible tablets (20 x 50 mg) (test IMP) and hydroxycarbamide film-coated tablet (1000 mg) (reference IMP) following single-dose administration. Thirty (30) healthy male and female participants, between 18 and 50 years of age are planned to participate in the study. Study participants will be randomised to one of the 2 possible combination sequences. After each treatment administration, blood samples will be collected at specific time points to assess the Pharmacokinetics (PK) parameters.

• No clinically significant abnormal test results for serum biochemistry, haematology and/or urine analyses within 28 days before the first dose administration of the IMP.
• Participant with a negative urinary DOA screen (including alcohol) test results, determined within 28 days before the first dose administration of the IMP.
• Participant with negative human immunodeficiency virus (HIV), hepatitis B surface antigen (HBsAg) and hepatitis C virus antibody (HCV Ab) test results at Screening.
• No clinically significant abnormalities in 12-lead ECG determined within 28 days before the first dose of IMP.
• No clinically significant abnormalities in vital signs determined within 28 days before the first dose of IMP.
• Participant must be available to complete the study.
• Participant must satisfy an Investigator about his/her fitness to participate in the study.
• Participant must provide written informed consent to participate in the study.

You may not qualify if:
